It all began one morning in the smoking room of the Department of Health and Welfare. That was where happily married Jack met the lovely Grace. At first smoking was all they had in common. But soon they were sharing a lot more. Love, as well as cigarette smoke, was in the air. But when Miriam, Jack's wife, began to suspect that his feelings had changed everything became a lot more dangerous. Because Miriam was a woman who liked to get her own way, and this time she was playing to win.
